SGM4073

Reset Timer with Integrated Load Switch

GENERAL DESCRIPTION

FEATURES

The SGM4073 can be used as reset timer as well as

load management switch. The device is very suitable

for highly integrated applications.

 Supply Voltage Range: 1.5V to 5.5V

 Factory-Set parameters:

 Reset Delay Time: 7.7s

 Reset Pulse: 468ms

When the mobile device is turned off, press the start

key to keep the PMIC at a logic low level for 1.9s to turn

on the PMIC.

 Turn-On Time: 1.9s

 Turn-Off Delay: 7.7s

 Adjustable Reset Delay Time

 6A Maximum Continuous Current

 20mΩ (TYP) On-Resistance at V_BAT= 3.6V

 Output Capacitor Discharge during Reset Period

 Slew Rate or Inrush Control with t_R: 3ms (TYP)

 Enable Zero-Second Test

Since the Quiescent Current of the SGM4073 is as low

as 1μA (TYP), it supports direct interface with

low-voltage chipsets and can maintain low power

consumption.

When the device is used as

reset timer,

 Available in a Green WLCSP-1.31×1.62-12B

Package

disconnecting the PMIC from the battery power for

468ms will produce a fixed delay time of 7.7s. The

delay time can be adjusted by an external resistor

connected between the DELAY_ADJ pin and ground.

APPLICATIONS

The SGM4073 also can be used as

load

management switch. It can disconnect loads with high

shutdown current and high load capacitance (< 200μF)

SGM4073 provides a 20mΩ on-resistance when V_BATis

3.6V.
